Great thread, great work as well. All of it, excellent and great to see. Had it not been for this thread and this forum we wouldn’t be aware of this craftsmanship at all, great idea to start it. I really admire craftsmanship and love creativity as well.
Yes.. you're right the cam arrangement is very interesting and such a simple, clean & tidy solution to the problem. Although it would seem both exhaust & inlet valves have the same amount of lift & duration as they are using the same cam. And I'm not knowledgeable enough to know how this might affect the engine's performance & capability. The wikipedia page for radials has a great schematic that helps a good deal. https://en.wikipedia.org/wiki/Radial_engine
I should have explained it better. There are 2 cams for the inlet valves and 2 for the exhaust valves.
Doh!.. I'm not sure it was your explanation rather than my viewing & interpretation of that schematic on wikipedia.... because after looking closely it does show two separate cam rings. V.clever all the same.
@higgy748 my brother is into painting planes. He is an AGAvA (associate?). https://gava.org.uk/galleries/2022-gallery/ I expect you are aware of them.
Wow some serious talent on this forum. Unfortunately I haven’t found mine yet unless you count reading to my Canadian nieces and grandson in my exaggerated English accent.
As promised, and in a bid to lower the quality of the items on show here is the chicken run I built. Note the concrete 'godfathers' used for the posts, wire that is buried into the ground, copious wire for the roof and millimeter perfect fitted door. Oh... and in the far distance a little bin action.
Totally bowled over by all your accomplishments, there are so many skilled and talented members on this forum! Here are some of my amateur efforts, which I hope are worthy of this thread. I wish I could make a living from doing this sort of stuff. But I'm not formally trained in any of it, so I lack the confidence. Wood and Coal store, built using free wood Large woodstore, again practically zero cost Coal store built for a friend. Lined with some left over Visqueen, and topped off with surplus roof felt. Refurb of some spare alloys, which were badly corroded. Total cost about £10-£15, for etch primer and Auto Glym Wheel Silver (highly recommended). Plus a pot of elbow grease. I made this Robert Planter using C24 pressure treated timber. Cost about £25-ish for the wood. My first "chop saw" project. Bass guitar repair and refurb Brake disc refurb using Hammerite Smooth Gold First attempt at bathroom tiling. 80cm tiles are tough to work with! Measure twice and cut once etc..
